Ballistix Tracer memory features two rows of eight "chasing" red and green
LEDs atop the module, circulating at varying speeds proportional to usage. A
custom-designed circuit relays bus activity to the LEDs, allowing them to
accurately reflect usage of each memory module by the rate of change of the LED
indicators. In addition, eight blue ground-effects LEDs emit a constant glow
near the pins.

"The introduction of the Ballistix Tracer memory series takes Crucial¿s
high-performance memory to a whole different level," said John Stroozas,
Crucial¿s Director of Engineering. "Tracer modules are for the hard-core
enthusiasts demanding not only the best possible stability and performance, but
also the revolutionary visual effects that set Tracer modules apart from the
competition. The activity-indicating LEDs offer our customers the opportunity to
identify which games and other applications make their Tracer memory work the
hardest."
